IO::TieCombine(3) User Contributed Perl Documentation IO::TieCombine(3)NAMEIO::TieCombine - produce tied (and other) separate but combined
variables
VERSION
version 1.000
SYNOPSIS
First, we set up a bunch of access points:
my $hub = IO::TieCombine->new;
my $str_ref = $hub->scalar_ref('x');
my $fh = $hub->fh('x');
my $callback = $hub->callback('x');
tie my $scalar, $hub, 'x';
tie local *STDOUT, $hub, 'x';
tie local *STDERR, $hub, 'err';
Then we write to things:
$$str_ref .= 'And ';
print $fh "now ";
$callback->('for ');
$scalar .= 'something ';
print "completely ";
warn "different.\n";
And then:
$hub->combined_contents; # And now for something completely different.
$hub->slot_contents('x'); # And now for something completely
$hub->slot_contents('err'); # different.
METHODS
new
The constructor takes no arguments.
combined_contents
This method returns the contents of all collected data.
slot_contents
my $str = $hub->slot_contents( $slot_name );
This method returns the contents of all collected data for the named
slot.
fh
my $fh = $hub->fh( $slot_name );
This method returns a reference to a tied filehandle. When printed to,
output is collected in the named slot.
scalar_ref
my $str_ref = $hub->scalar_ref( $slot_name );
This method returns a reference to scalar. When appended to, the new
content is collected in the named slot. Attempting to alter the string
other than by adding new content to its end will result in an
exception.
callback
my $code = $hub->callback( $slot_name );
